Yes. You can change how many meals you get from your account - the change takes effect from your next delivery, and the system will show you the new price before you confirm. Switching between single-day and split (twice-weekly) plans is an admin-mediated change for now - email us at hello@viva.je and we'll arrange it for your next cycle.
We currently have a minimum of 5 meals per delivery to support our free delivery model. Beyond that, you can choose whatever quantity works best for you. Many customers also split their plans across Sunday and Wednesday deliveries to keep everything extra fresh.
Meal-count changes apply from your next delivery, not the current one. If you've already passed the cut-off for the upcoming delivery, your current count stays for that one and the new count kicks in from the delivery after. Your account shows the price preview and the effective date before you confirm.
